CALIFORNIA 7 OIL BURNER Application filed May 15,

Our inventionrelates to improvements in oil burners, and more particularly to atomizers for oil burners, and the principle of which may be used'for other purposes, such as gas and air burners, water sprinklers and the like.

In oil burners of the type using oil which is preheated and under pressure, thorough atomization and spreading is required for the most eflicient heat in the furnace, and

. the object of this invention is to provide an atomizer'of greater efliciency.

Another object is to improve the construe tion of the tip or nozzleto receive the atomizer element and to provide means of clamping the two on the end of an oil feed pipe.

Another object is to provide a double thread to give the oil a. rotary as well as forward movement, and at the same time avoid the retarding effect on the fiow of oil.

. Other objects will appear tothose skilled,

and clamping nut, on the end of a pipe, and

Figure 4 is a detached, enlarged, end view of the atomizer. v

The numeral 1 indicates the head of the burner, into which is screwed. the pipe 2 threaded at both ends, as shown at 3 and 4. On the end thread 4 is a clamping nut 5. The HtOIIIlZGI' COIISlSlSS of the flange 6, having the stud 7 integral therewith, the end of the stud being cone shaped as at 8. On the stud are formed square double threads 9 and 10 forming the grooves 11 and 12 through which the oil flows from the hole 13 which receives the oil from the pipe 14: through the opening 15. The tip 16 has the flange 17, which is clamped against the flange 6 on the end of the pipe. The opening 18 fits over the 1930. Serial No. 452,757.

outside of the threads, and cone shaped opening 19 allows space around the cone 8, for a the flow of oil around thevcone, and through the tip opening 20. In operation the oil flows from the pipe through the openings and '13 and comes out on both sides of stud and is whirled around the grooves 11 and 12 and out over the cone, and through the tip opening which imparts a rotary or whirling motion just before it reaches the tip hole, and it leaves the tip-opening in a cone shaped spray, and thus a very efiicient heating flame is produced.

The use of two square threads was found to be more efficient than a single thread or a number of threads in the atomizer.

Having thus described our invention, What we desire to secure by Letters Patent'of the United States i-sas follows, but modifications [may be had in carrying out the invention as shown in the drawings and in the above particularly described form thereof within the purview of the annexed claims.

We claim e 1. An oil burner comprising in combination an oil supplypipe, a flanged member on the end'of said pipe, a stud on saidflanged member, double screw threads on said stud, a

transverse opening through said stud leading to each of said threads, said opening having a connection with the oil supply pipe, a

fianged'tip mounted on. said flanged member, and means toclamp both of said flanges to the end of the pipe. j

2. An oil burner comprising a flanged atomizer, a flanged tipfitting over said atomizer, andbothflanges one on the other being clamped to the end of an oilsupply pipe.
